Outdoor Pic of the Day – Boulder Flatirons
The Flatirons are a group of rock formations in the western United States, in Boulder, Colorado, that are made up of flatirons and other irregular shapes. A group of five huge, numbered Flatirons may be found on the east slope of Green Mountain, running north to south from north to south. The phrase “The Flatirons” is sometimes used to refer to just these five Flatirons.
